Sharepoint Calanders counted recurring appointments

[surfernat]

Hi Everyone
I have been tasked with setting up a personnel calander in Sharepoint which shows the number of years service each employee has completed.

I have managed to setup the recurring appoitment showing the anniverary date of the date started but I want to show how many years that person has been there.

IE
Joe Bloggs Recruit Anniversary 1 year
Joe Bloggs Recruit Anniversary 2 year

Is there a bit of code or something I can paste in the calander title that adds an appoinmnt count if you know what I mean .

Thanks
sorry if not very clear!
